I'm sure Guitar Hero players gain better rhythm over time too. However, will their musical skills be as good as someone who actually take the effort to learn guitar? Probably not. I agree with you that the author ignored some important facts. However, the thesis still holds that many achievements (i.e. education) have been dumb down to make people feel content about being less skilled. The problem is that we are getting better at hacking our own brains to give us more reward than we deserve.
